TMSAT-1 multispectral images



I have now posted 5 multispectral images to the web site -:
http://www.ee.surrey.ac.uk/EE/CSER/UOSAT/amateur/tmsat/index.html

These images are each over 500kb.  They are saved as JPG files so there is
some minor image quality loss associated with this, however this is probably
more desirable than downloading the full image which is approximately 3.5MB!

The multispectral image was produced by combining the data from the three
Narrow Angle Camera, sensing in the green, red and near-IR spectra.  Each
image has 1020 x 1020 pixels, covering an area of 100 x 100 km at mean
ground resolution is 98 metres / pixel.

Red areas indicate healthy vegetation (due to the strong near-IR reflectance
of chlorophyll).  Urban areas are generally blue-grey.  The different
colours of fields provides an indication of the state of vegetation (bare
soil, marsh, young or mature vegetation, etc).
